I did a search and couldn't find anything, so here goes...
Premiere Video, an independent video rental store in Dallas, TX, offers the rental of an HD DVD player for $10. I'm not sure which player it is (I suspect it is the A1) or how long the rental period is (I suspect two nights - the same period as their standard rentals). The owner explained to me tonight that he is doing it to raise interest in the "new formats" and "get people to try them out." Yes, he intends to do the same thing for Blu-ray when it is available. That's how I'll sample Blu-ray when it comes out.
They also have several HD DVDs to rent - most of the Warner offerings, Serenity, and maybe more (some could have been rented out) for $3.50/two nights rental. They didn't get Firewall in today as it was delayed by their distributor.
They're located at 5400 E. Mockingbird at Central Expressway.
